IMPROVEMENT IN VISES.

A Specification forming part of Letters Patent No. 209,142, datedOctober 22, 1878; application filed April 1, 1878.

'To all whom it may concern:

jaws.

Figure 1 of the accompanying drawing is an elevation, part in section,of a vise in the usual vertical position mounted on a swivel inaccordance with one form of my invention. Fi g. 2 is an elevation of thesame, showing the vise turned about its axis 00 a: a half-circle fromits formerposition, the jaws now being horizontal.

A is the bed-piece, either cast as a part of the body of the vise, or,as here represented, made separate, to be attached to the body of thevise in any suitable manner.

B is the base-piece, which is secured to the bench I). The bed-piece Ais arranged to, turn upon the base-piece B on an axis inclined to theplane of the jaws, and the two parts may be secured together at anydesired point of revolution, thus fastening the vise to the bench inthat position. There are many ways in which the parts A and B can bearranged to operate on this principle; but Iprefer the one here shown asthe most simple and efficient.

The lower face of I the bed-piece A and the upper face of the base-pieceB come to abearin g in a circular form on a plane, 3 y, at right anglesto the axis of revolution 00 m. The bolt 0 is'concentric with the axisof revolution, and when it is loosened the bed-piece A revolves freelyupon it; but it may be tightened by the usual screw and nut, securingthe bed-piece A to the base-piece B in any desired position. This kindof attachment is commonly called a swivel, and should greater range ofadjustment of positions to the vise be desired, the vise may be attachedto the bed-piece A by such a swivel.

The axis of revolution of my vise will be usually fixed at forty-fivedegrees inclination to the plane of the jaws, that being the anglerequired to revolve the vise-jaws from a vertical to a horizontalposition.

For special purposes vises may be made on this principle, with. the axisfixed at other angles.

I am aware that "ises are common which turn upon an axis parallel to theface of the jaws, that others turn on an axis perpendicular to the faceof the jaws, and that others have a ball-and-socket adjustment notcapable of giving the jaws both a vertical and horizontal position; but

I claim as my invention- A bench-vise arranged to turn upon an axisinclined to the plane of the jaws, so that the vise may be set with itsjaws in either a-practically vertical or horizontal position,substantially as and for the purpose specified.
